Enabling Journaling
By default, journaling is enabled for the InterSystems IRIS® data platform databases IRISSYS, IRISAUDIT, and USER. You can enable or disable journaling on each database from the Local Databases page of the Management Portal (System Administration > Configuration > System Configuration > Local Databases). Click Edit on the row corresponding to the database and click Yes or No in the Global Journal State box.
The default setting of the journal state for new databases is Yes. When you first mount a database from an earlier release of InterSystems IRIS, the value is set to Yes, regardless of the previous setting for new globals and regardless of the previous settings of individual globals within that database.
You can change the global journal setting for a database on a running system. If you do this, InterSystems IRIS warns you of the potential consequences and audits the change if auditing is enabled.
